GE / IP FANUC Series 90/30 In Stock
This troubleshooting guide is a test of the GE Fanuc IC697CPU732 90-70 processor in an IC697CHS750 five slot rack which is empty, powered by an IC697PWR711 power supply and the CPU is powered up.
The first thing you are looking for right here is the OK light that’s the top light LED and it should be on and solid. If so, that’s a good sign. If it’s blinking or you don’t have the OK light then you definitely have a problem with your processor and you won’t be able to follow this test. If this is the case check at the bottom of this page for links to parts and service.
So, now that you do have that CPU OK LED light on you are going to go ahead and get connected up to it using Proficy Machine Edition GE software and you hit the lightning bolt icon and connect up
and then go into program mode and top menu bar. You then click Target go down to Online Commands and within Online Commands you’re going to go to Clear. Then a Clear Memory window will pop up, what you want to do is select Controller Fault Table and I/O Fault Table and clear those.
DON’T clear anything else because you could risk losing something that you need to keep. Now you are going to go ahead and click OK, again Controller Fault Table and I/O Fault Table, and once that clearing is successful you are going to hit Download and Run ie: the Download Information and Run button. Keep in mind that in Rack 0, which is what is illustrated here, you want to make sure there’s nothing else in the rack otherwise you’re going to have a fault.
So, now it’ll ask you “what do you want to download to the controller?” Just logic and hardware, nothing else. This is just a simple test for the CPU and the goal here is try to keep the CPU in Run mode and then to test one of the features of the other processor. Okay, so it should now be on.
Now the top LED (see image above) is the OK LED the next one down is RUN mode and the third one down, the bottom LED is I/O enabled and you can use the toggle switch here to turn on and off these
features so it’s a three position switch.
In this illustration the toggle switch is starting out in the top position. When you drop down one you are looking for the LED with the I/O enabled shut off. So if that’s working the next step down in the bottom position which says the Run is disabled and you can see using these LED’s that this feature works. So, that’s the basic test for the IC697CPU732.
If you think there’s a problem with this CPU its a good idea to let it run overnight or over a weekend or a couple days and what you’re hoping to see is that the processor stays in run mode and it doesn’t kick itself out.
If it does kick itself out, then there’s some sort of a problem and what you want to do if it’s kicked out is go into your Proficy Machine Edition go to Target at the top menu bar and towards the bottom there’s a diagnostics screen you can view and it will pop up with a fault table and will describe whatever fault occurred or whatever error it was that made the processor jump out of run mode.
